Dual-coil localization with intentional pneumothorax for pulmonary nodule resection in pediatric patients: a novel technical approach.
Article in Pediatric radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Intraoperative identification of small, non-palpable pulmonary nodules during video-assisted thoracoscopic surgery (VATS) remains challenging in pediatric oncology patients. We describe a novel dual-coil CT-guided localization technique in which a controlled pneumothorax is created via a parallel needle, a small coil is anchored deep to the target nodule as a fluoroscopic margin reference, and a longer coil is deployed with its terminal segment suspended freely within the pleural space to provide immediate thoracoscopic surface identification. In three consecutive pediatric oncology patients, technical success was achieved in all cases with direct thoracoscopic coil visualization, fluoroscopically confirmed negative resection margins, and no conversion to open thoracotomy. No major complications occurred. Prospective validation is warranted.
